i am currently running in my GN a te 34 turbo(engraving says j4 34), race underdrive pulleys, 40# injectors, some race chip but can't identify it, 70mm throttle body, lower intake ported out, mild head work, adjustable wastegate, dump pipe off turbo, 3200 stall, two fuel pumps, stock intercooler. 11.83 @115 with 20# of boost.
i need some assistance on where to go next to get the car down into the low 11s eventuallly high 10s. maby 50# injectors intercooler??? the cage and suspension are going to be done next week.
also the turbo in my car doesn't seem to spool up till about 2800 rpm and maxes at 14 pounds of boost with foot brake at the line. i once had a 12 inch converter with a stall a litttle higher than stock stall speed and could only get like 2 to 4 # of boost with s10 brake cylinders. with a 3200 stall the tubo works spools up much better. to my understandiung the turbo on my car should be building boost around 2500 to 2800(possibly a different compressor in the housing). maby i am wrong but in any case any help is appreciated
thanks,
Don Wigginton
